Berahino scored the winner in the Baggies' 2-1 victory over Manchester United at Old Trafford last week to add to the four goals he has netted in the Capital One Cup this season.

Clarke accused the 20-year-old's agent of revealing that the forward only earns £850 a week at The Hawthorns.

"Seeing what came out in the press after the game last week, obviously his agent has been a little bit busy by putting things out in the open," Clarke said.

"I understand that it's an agent's job and that's what he has to do, but now is the time for everyone to be calm and focus on improving Saido as a player.

“It was a little bit naughty for the agent to put out the level of his wages and what he earns”

"It was a little bit naughty for the agent to put out the level of his wages and what he earns. It's not correct.

"But if Saido continues to do what he's doing, he'll be looked after here. No problem."

West Brom are currently in talks over a new deal for Berahino, who under the terms of his current deal could leave in 2015 for just £300k in compensation.

Arsenal, Chelsea and Everton are all weighing up a move for the talented forward in the new year and Berahino will hope to have another chance to impress when the Baggies entertain the Gunners tomorrow afternoon.
